Ordered this a couple of days ago and it arrived today. Steelbook is actually quite good if not a little odd.
So the front has a frame and the Titans hand is embossed (or the rest of the image is debossed... Whatever you prefer) but is a matt finish while the back has the whole Titan spot glossed as well as the rubble. Didn't find it the easiest to capture the gloss on the back in the pictures for some reason.
I really like the inside art too. Check the spoiler for all images that show the bossing and the glossing.
